Title: Stator laminated thin plate for electric machine
Inventor: YURUGEN BEEA
IPC: H02K1/20
Filed: 1995-06-27
Abstract: PURPOSE: To greatly decrease fluid resistance in a stator cooling slit by radially boring a hole in the inside end part of a spacer wave and interrupting the spacer web at a position, where the hole links circumferentially adjacent partial passages with each other. CONSTITUTION: A hole 14 is bored in the radially inside end part of a spacer web 3 which partitions partial laminate thin plate bodies constituting a stator laminate, and the spacer web 3 is interrupted, where the hole 14 links circumferentially adjacent partial passages 4a and 4b with each other. This hole 14 or interrupt part slants almost in parallel to the flow direction of a cooling gas. Consequently, the fluid resistance in the stator cooling slit is decreased to reduce or avoid a large constriction of a flow at an entrance to a cooling passage. Further, a relatively large dynamic pressure at this position is converted into static pressure. Consequently, a return flow of the cooling gas can be avoided.
